This invention relates to pad boxes, 'that is, to supports 'for a yielding pad as used in 'applying pressure to shoe bottoms, for example, in the cement-attachment of soles to shoes;

'Usually a thick pad contoured to correspond to the transverse curvature of the .shoe bottom is employed with a support adjustable to the longitudinal contour of the shoe bottom. Objects of this .invention are to provide a ,pad support having transverse as well as longitudinal contours and which may be adjusted so that a thin yielding pad may ibe used therewith the function of which is to take care only of the minor differences between the contour of the 'pad and that of the shoe bottom, thus efiectin economy in the use of relatively shortlived rubberlike materials used for the pad, and .also to provide a pad support the transverse contour of which at the shank portion may be varied relatively to that of the forepart, the shank portion usually having the greater curvature.

To provide for 'adjustment of the longitudinal curvature `of the pad support to correspond to the longitudinal curvature of the shoe bottom, transverse pivots in the support are .located one at each end of the shank portion. fIhen, by fixedy supporting the heel end .heightwise and variably supporting the heightwise positions of the ball joint and the iorepart of the pad support, its longitudinal contour may be made complemental to the longitudinal curvature of any shoe bottom, that is, to the bottom of any shoe irrespective of the height of the heel which it is to .have.

The variations of the transverse curvature of the pad supporting may be accomplished, as illustrated, by making the support of a pluralityof independent longitudinally extending sections each having a pivot at each end of the shankengaging portion and by providing a curved surface complemental to the transverse curvature of the forepart of the shoe bottom under the .forepart of the pad support and another support under the ball joint of the sections complementary to the transverse curvature of the shoe .bottom at the ball and shank. Since the sections are independent, they are shiftable relatively to each other longitudinally of the shoe to take care of any rearward curvature .of the shoe bottom at the ball line. The longitudinally extending sections of the pad support may be made as numerous as desired, the greater the number the more closely they .can be made to correspond to the transverse curve of 'the shoe bottom.

'These and other features :of the --inventioh will appear more fully from 'the rohowing ;description when read in connection withthe 'accompanying drawings and will be pointed out'inthe appended claims. v

In the drawingsi Fi'g. 1 is a perspective view of 'the pad 'boxand pad support;

Fig. 2 is a detail of a prismatic .member which engages the pad support 'under 'the ball :line:

Fig. 4 is a sectional 'View on 'the line ;LV- IV of Fig.'5;

Fig. '5 is 'a perspec'tive *view 'of one of ethe :sections compris'ing the pad support Fig. 6 is a side elevation, partly in section., showing the pad support-adustedsfor ashoe that is 'to have a highheel; and

Fig. 7 is a view similar to Fig. 6 showing the support adjusted for a shoe having `a .relatively flat bottom.

The support 'for a pad 8 comprises a pluraiity, or even a multiplicity, oflaterally narrow,;1ongitudinally extending sections IU -(F'ig. .5)'o suicient heightwise extent to provide the necessary strength to resist the applied pressure. Each of the longitudinally extending sections has three portions, aheel portion 12, 'a shank portion !4 and a forepart portion !6. Each of the sections (eighteen of which are shown in the drawings) has two flush joints, one, [8, substantialiy under the ball line of a shoe placed thereon and another, 20, under the heel breast :line of .the shoe. i

.In making the joints l8 and '20, the shani; portion [4 is rounded a't each end, one end 'being received by a complementary recess in the heel portion l2 and the other end being received 'in a complementary 'recess in the forepart portion !6. Plates, comprising a circuiar portion 22 and a stem portion 24,are p1aced one *on each side of the joint between 'the adj'acent portions of each section o with 'the circular 'portion 22 concentric with the curved end of the shank section and with the st'em 24 over'lying theadjacent heel or forepart portion. ;Each ;plate-.is recessed into the adjacent ,portions so as to. be fiush with their surfaces, the stern 24 being secured by rivets 26, and the joints being formed by a rivet 28 (Fig. 4) (which may be a hollow rivet) put through the center of the circular 'portions of the plates and through an end ;portion of .the shank 'section to form'th'e .joint. .The end portions of each shank portion 14 arie cu t sections each having two joints one at the ball line and one at the breast line, means supporting the heel portion's of the sections heightwise, a support for the ball line joints of the sections, a support for the foreparts of the sections, and means for varying the heightwise POStOBgO the ball line support to vary the longitudinal curvature of the sections.

9. A pad support for use in applying pressure to shoe bottoms comprising a series of longtudinally extending, juxtaposed, pad-supporting sections each having a joint at the ball line and at the breast line thus dividing each section into e. forepart portion, a shank portion and a heel portion, a fixed support sustaining the heel portions of the sections heightwise, a support for the ball joints of the sections comprising a prismatic REFERENCES CITED The following references are of record in the file of this patent:
